HIGH INTENSITY DISCHARGE HEADLAMPS

(HID) — IF EQUIPPED

The headlamps are a type of high voltage

discharge tube. High voltage can remain in the

circuit even with the headlamp switched off and

the key removed. Because of this, you should not

attempt to service a headlamp bulb yourself. If a

headlamp bulb fails, take your vehicle to an

authorized dealer for service.

NOTE:

On vehicles equipped with HID headlamps, when

the headlamps are turned on, there is a blue hue

to the lamps. This diminishes and becomes more

white after approximately 10 seconds, as the

system charges.

HALOGEN HEADLAMPS — IF EQUIPPED

NOTE:

Lens fogging can occur under certain atmospheric

conditions. This will usually clear as atmospheric

conditions change to allow the condensation to

change back to vapor. Turning the lamps on will

usually accelerate the clearing process.
See the following steps to replace:
1. Open the hood.
2. Access the back of the headlamp.
3. The air filter housing must be removed.
4. The windshield washer reservoir may need to

be rotated out of the way by removing the

fastener.

5. Coolant reservoir (if equipped) will need to be

repositioned by removing the fasteners, and

moving the unit out of the way.

6. To access the low beam bulb you must remove

the rubber boot seal from backside of the lamp

housing.

Rubber Boot Seal

NOTE:

Ensure the rubber boot is properly reinstalled to

prevent water and moisture from entering the

lamp.

WARNING!

A transient high voltage occurs at the bulb

sockets of High Intensity Discharge HID

headlamps when the headlamp switch is turned

ON. It may cause serious electrical shock or

electrocution if not serviced properly. See an

authorized dealer for service.

CAUTION!



Do not contaminate the bulb glass by touching

it with your fingers or by allowing it to contact

other oily surfaces. Shortened bulb life will

result.



Always use the correct bulb size and type for

replacement. An incorrect bulb size or type

may overheat and cause damage to the lamp,

the bulb socket, or the lamp wiring.

Tire And Loading Information Placard

Tire And Loading Information Placard

This placard tells you important information about

the:
1. Number of people that can be carried in the

vehicle.

2. Total weight your vehicle can carry.
3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the front, rear,

and spare tires.

Loading

The vehicle maximum load on the tire must not

exceed the load carrying capacity of the tire on your

vehicle. You will not exceed the tire's load carrying

capacity if you adhere to the loading conditions,

tire size, and cold tire inflation pressures specified

on the Tire and Loading Information placard

SERVICING AND MAINTENANCE

297

To determine the maximum loading conditions of

your vehicle, locate the statement “The combined

weight of occupants and cargo should never

exceed XXX kg or XXX lbs” on the Tire and Loading

Information placard. The combined weight of

occupants, cargo/luggage and trailer tongue

weight (if applicable) should never exceed the

weight referenced here.

Steps For Determining Correct Load

Limit—
(1) Locate the statement “The combined

weight of occupants and cargo should

never exceed XXX kg or XXX lbs.” on your

vehicle's placard.
(2) Determine the combined weight of

the driver and passengers that will be

riding in your vehicle.
(3) Subtract the combined weight of the

driver and passengers from XXX kg or

XXX lbs.

(4) The resulting figure equals the

available amount of cargo and luggage

load capacity. For example, if “XXX”

amount equals 1400 lbs. and there will

be five 150 lb passengers in your

vehicle, the amount of available cargo

and luggage load capacity is 650 lbs.

(1400-750 (5x150) = 650 lbs.)
(5) Determine the combined weight of

luggage and cargo being loaded on the

vehicle. That weight may not safely

exceed the available cargo and luggage

load capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer,

load from your trailer will be transferred

to your vehicle. Consult this manual to

determine how this reduces the

available cargo and luggage load

capacity of your vehicle.

Metric Example For Load Limit
For example, if “XXX” amount equals 635 kg and

there will be five 68 kg passengers in your vehicle,

the amount of available cargo and luggage load

capacity is 295 kg (635-340 (5x68) = 295 kg) as

shown in step 4.

NOTE:



If your vehicle will be towing a trailer, load from

your trailer will be transferred to your vehicle.

The following table shows examples on how to

calculate total load, cargo/luggage, and towing

capacities of your vehicle with varying seating

configurations and number and size of occu

-

pants. This table is for illustration purposes only

and may not be accurate for the seating and

load carry capacity of your vehicle.



For the following example, the combined weight

of occupants and cargo should never exceed

865 lbs (392 kg).
